IMPROIEMENT IN ALARM FOR CARDING-MACHINE.

TO-ALL WHOM IT MAY CONCERN:

Be it known-that we, JOSEPH HAYruonN and CHARLES E. PRICE, both of'.lhompsonvlle, Hartford county, State of Connecticut, have inventedanew and useful Improved Attachment for Cardi ngMachines; and we dohereby declare that the following is a full and clear descriptionthereof, reference being had to the accompanying drawings, and to theletters lor" reference markedthercon.

' In the drawings- Figure 1 is an end view and partial sectional view ofmy device,

Figure 2 a side' view, partly in section, and A Figure 3 aplan view ofthe same, @i

yFigure 4 being a d etail view of one of the parts pertaining thereto.

This invention consists of a new and useful improvement incarding-machines, whereby the operator is warned of -the breaking of astrand before it is fed into the machine..

In construction, we form our device as follows A About a foot and ahalfI back from the feed-rolls we placetwo pair of rolls, B and C, a fewinches apart, each pair having the strands a a a, Svc., topass betweenthem. Between these 4pairs of rolls, B and C, are .arranged verticalposts, 6 b, tc., one post for each strand.v The strand passes 'through afunnel-shaped opening in the top of thepost, holding the latter down, itbeing operated by a spring,-D, so Vthat 'it constantly presses up. Theconstruction of this post may be varied; however,'without altering theprinciple involved.

- At the lower end of each of the posts, below the frame E, in which thesprings are arranged, is a slot, c, through which a cord, F, extendsacross ,the bed of the machine,being xed at one end, and attached at`thc other to a bolt or .pin,.G, which it draws inwards when any unusualtension is put upon the cord.

Resting upon this pin G is one end of a lever, H, pivoted near the otherend to the side of the machineframefI. At the shorter end is hung abell, J, the weight of which docs'not overbalance or even equal theweight of the longer vend of the lever. i I

Upon the tumbler-shaft K, is a pulley, with-a pin, L, or a crank orequivalent device, for the purpose of agitating thev bell whenthe-shorter end of the lever is brought within-reach of-it.

The operation of this device is as follows:

`When'one of the strands breaks, it lets the post corresponding withV itily up, andthe lower end of it pulls up the cord-.attached to the bolt,as shown in fig. 1A. The lever, having its rest removed, falls, thelonger end downwards, bringing the shorter end, with thebell, withinreach of the crank, which agitates it as the tumblershaft revolves, andrings the bell. y

The advantages of this device are, that. the operator is enabled todiscover the' broken strand, and have plenty of time to mendit,before'it reaches the feed-rolls; and this applies to nearly all cases,for the strands rarely ever `break after the feed-rolls have beenpassed, and the spring on the post being made of just the properstrength to be held d'own by a sound strand, prevents imperfect onesfrom passing this point.

Having described our invention, what we claim as new,` and desire tosecure hy Letters Patent, is?- The combination of the rolls B and C,spring-posts b b, cord F, with bolt G, and lever H, with its bell, allarranged substantially as described, and applied to a ending-machine,for the purpose set forth.
